According to Outsystems documentation, InAppBrowser plugin is not supported in PWA. So thought of creating this simple approach which helps to open the URL within the native and PWA app rather than taking the user away from PWA app to open external links.
Implementation is very simple.
That's it :)
Please note: This approach uses Iframe to open the external URL, so make sure the external site has the right settings to enable Iframe access. For example, Google has disabled this settings, so https://google.com cannot be opened in Iframe. So, it's worth checking.
